AIM This study was performed to evaluate the efficacy, safety and complications of electrotherapy compared with conventional hemorrhoidectomy (Ferguson technique). BACKGROUND Ferguson hemorrhoidectomy is always associated with considerable pain and postoperative complications.

This study aimed to evaluate the efficacy of the LigaSure vessel sealing system (LVSS) when used for esophagectomy. We compared 56 consecutive patients (32 male and 24 female, mean age: 56.64"12.61 years), who had undergone Ivor–Lewis esophagectomy for esophageal carcinoma between January 2005 and May 2009. Among them, from January 2005 to April 2007, 27 patients (group 1) were operated on with...
